Dear Internet Archive Patrons,
We need your help to make sure the Internet Archive lasts forever. On November 9, we woke up to a new administration promising radical change. This is a firm reminder that the Internet Archive must also design for change. So we set a new goal: to create a copy of our collections in the Internet Archive of Canada. This will cost millions. For us, it means keeping our cultural materials safe, private and perpetually accessible. It means preparing for a Web that may face greater restrictions. It means serving patrons when government surveillance may be on the rise. The Internet Archive is a non-profit library built on trust. Reader privacy is very important to us, so we don’t accept ads. We don’t collect your personal information. But we still need to pay for servers, staff and rent. If everyone reading this gave $50, we could end our fundraiser right now. If you find us useful, please give what you can today. Thank you.

Hubble was designed to use three of six onboard gyroscopes to meet its very precise pointing requirements, with the other three held as spares. Gyros have limited lifetimes, and three of the six (all installed in late-1999) are currently working. Following a thorough analysis and testing by engineers, it was determined that Hubble could operate productively on two gyros. After the implementation of three new control modes in Hubble's main computer, and major changes to Hubble's planning and...
